Requirements NIST SOURCE

Provide an explicit indication of current participants in [online meetings and teleconferences].

Discussion (NIST Supplemental Guidance)

Explicitly indicating current participants prevents unauthorized individuals from participating in collaborative computing sessions without the explicit knowledge of other participants.

Implementation Guidance

Engineering Interpretation

Original engineering commentary written for this explorer — not NIST source text and not authoritative guidance.

No engineering interpretation has been authored for SC-15(4) yet. This section is architected to receive it — see the Requirements and Assessment sections above for the authoritative NIST source content in the meantime.

Assessment

NIST SP 800-53A REV 5.2.0

Assessment Objectives

online meetings and teleconferences for which an explicit indication of current participants is to be provided are defined;
an explicit indication of current participants in <SC-15(04)_ODP online meetings and teleconferences> is provided.

Examine

[SELECT FROM: System and communications protection policy; procedures addressing collaborative computing; access control policy and procedures; system design documentation; system configuration settings and associated documentation; system audit records; list of types of meetings and teleconferences requiring explicit indication of current participants; system security plan; other relevant documents or records].

Interview

[SELECT FROM: System/network administrators; organizational personnel with information security responsibilities; organizational personnel with responsibilities for managing collaborative computing devices].

Test

[SELECT FROM: Mechanisms supporting and/or implementing the capability to indicate participants on collaborative computing devices].

STIGs & CCIs

No STIG checks or CCI mappings are currently loaded for SC-15(4). This section is architected to display, per product: STIG ID, Finding ID, Severity, Title, Description, Check, Fix, CCI, and NIST control mapping — but nothing is populated here until a real DISA STIG/CCI dataset is ingested.
